- Physical maps are maps of locations of identifiable landmarks on a genomic DNA _______ inheritance patterns.a) remotely related tob) related toc) regardless ofd) associated withAttached are three pedigrees. For each trait, considerwhether it is or is not consistent with X-linked recessiveinheritance. In a sentence or two, indicate why or why not.A recently married man and woman discover that eachhad an uncle with alkaptonuria (black urine disease), arare disease caused by an autosomal recessive allele of asingle gene. They are about to have their first baby. Whatis the probability that their child will have alkaptonuria?
- Suppose a maternal effect gene exists as a functional dominantallele and a nonfunctional recessive allele that causes a disorder.A mother with the disorder produces offspring that are all withoutthe disorder. Explain the genotype of the mother.For a typical complex trait, describe the relationship betweenthe number of genes affecting the trait and the magnitude oftheir effects on the trait.What is the probability that a parent carryinga dominant trait will pass that trait on toeach child?
- Huntington disease is a rare dominant condition in humans that results in a slow but inexorable deteriorationof the nervous system. The disease shows what mightbe called age-dependent penetrance, which is to saythat the probability that a person with the Huntingtongenotype will express the phenotype varies with age.Assume that 50% of those inheriting the HD allele willexpress the symptoms by age 40. Susan is a 35-yearold woman whose father has Huntington disease. Shecurrently shows no symptoms.
